Answer:

the answer is he rode 17 miles in the morning and 40 miles in the afternoon

Step-by-step explanation:

so in the afternoon, it says that 6 more than twice as many miles in the afternoon as in the morning. this means that if the morning is x then in the afternoon it will be 2x+6 but it says altogether it is 57 miles so the you have to add x too.

so the equation is 2x+6+x=57

then this should be easy to solve.

2x+6+x=57

3x+6=57

3x=51

x=17

so if the morning is 17 miles then the afternoon will be:

2(17)+6

this equals to 40.

I hope that this is helpful!
